我知道有幾百億的關於RunTimeException的問題，當試圖開始活動，但我真的沒有找到我的問題的答案。RunTimeException當開始活動

我不明白很多關於LogCat但它說android.view.InflateException: Binary XML file line #17: Error inflating class，就是指的在activity_login.xml文件或什麼？

MainActivity.java：

public class MainActivity extends AppCompatActivity 
{ 
TextView textView1; 

Button hairCutsButton; 
Button sexButton; 
Button signUpButton; 
Button loginButton; 



@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    textView1 = (TextView) findViewById(R.id.textView_1); 
    textView1.setTextColor(Color.rgb(0, 0, 0)); 

    hairCutsButton = (Button) findViewById(R.id.hairCutsButton_1); 
    sexButton = (Button) findViewById(R.id.sexButton_1); 
    signUpButton = (Button) findViewById(R.id.sign_up_button_id); 
    loginButton = (Button) findViewById(R.id.login_button_id); 

    signUpButton.setOnClickListener(new View.OnClickListener() 
    { 
     @Override 
     public void onClick(View v) 
     { 
      Intent intent = new Intent(MainActivity.this,SignUpActivity.class); 
      startActivity(intent); 
     } 
    }); 
    loginButton.setOnClickListener(new View.OnClickListener() 
    { 
     @Override 
     public void onClick(View v) 
     { 
      Intent intent = new Intent(MainActivity.this,LoginActivity.class); 
      startActivity(intent); 
     } 
    }); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) 
{ 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) 
{ 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 
    if (id == R.id.action_settings) 
    { 
     return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 

public void moveToHairCutsActivity(View view) 
{ 
    Intent intent = new Intent(this,HairCutsActivity.class); 
    startActivity(intent); 
} 
public void moveToSexActivity(View view) 
{ 
    Intent intent = new Intent(this,SexAcivity.class); 
    startActivity(intent); 
}

}

顯然，當

Intent intent = new Intent(MainActivity.this,LoginActivity.class); 
startActivity(intent);

那些2線所執行的RunTimeException引起。

請幫幫我。

LognActivity.java：

public class LoginActivity extends AppCompatActivity 
{ 

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_login); 

} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) 
{ 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.login, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) 
{ 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 
    if (id == R.id.action_settings) 
    { 
     return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 
}

header_gradient.xml：

<?xml version="1.0" encoding="utf-8"?> 
<Shape xmlns:android="http://schemas.android.com/apk/res/android" > 

<gradient 
    android:startColor="#24b2eb" 
    android:centerColor="#4ccbff" 
    android:endColor="#24b2eb" 
    android:angle="270" 
    /> 
<corners 
    android:radius="5dp" 
    /> 

</Shape>

footer_repeat.xml：

<?xml version="1.0" encoding="utf-8"?> 
<bitmap xmlns:android="http://schemas.android.com/apk/res/android" 
    android:tileMode="repeat" 
    />

問題是'LoginActivity'，所以顯示'LoginActivity'活動和佈局xml –

@ρяσѕρєяK有佈局。我會添加活動。 – God

@ρяσѕρєяK它基本上是空的。 – God

在這裏：

<LinearLayout 
     android:id="@+id/linear_layout_header_id" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:background="@layout/header_gradient" <<<<< line 
     android:paddingTop="5dip" 
     android:paddingBottom="5dip"> 
... 
</LinearLayout>

目前從layout文件夾這是不正確的設置背景繪製。移動header_gradient文件夾drawable這是我們想要的任何view.then使用background使用可繪製，選擇和形狀合適的地方：

android:background="@drawable/header_gradient"

將它移動到drawable，但仍然在第17行獲得相同的LogCat。'android：background =「@ drawable/header_gradient」' – God

@God：在android：id =「@ + id/linear_layout_footer_id」所以也以相同的方式更改'android：background =「@ layout/footer_repeat」' –

我也改變了頁腳。還添加了header_gradient.xml文件。 – God

RunTimeException當開始活動
