Question

我在android studio上的项目在少数手机和模拟器上正常运行但在许多手机上都崩溃了。我有一个Main_Activity，点击登录进入第二个活动。我正在与android manifest共享这两个活动的java文件和xml文件。

主要活动Java文件

package club.pithynews.iitbhilai_pithy;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    private EditText username;
    private EditText password;
    private Button login_button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        java.text.DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
        LoginButton();
    }

    public void LoginButton() {
        username = (EditText) findViewById(R.id.editText);
        password = (EditText) findViewById(R.id.editText2);
        login_button = (Button) findViewById(R.id.button);

        login_button.setOnClickListener(
                new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        if ((username.getText().toString().equals("user"))&&(password.getText().toString().equals("pass"))) {
                            Intent intent = new Intent("club.pithynews.iitbhilai_pithy.User");
                            startActivity(intent);
                        }
                    }
                }
        );
    }
}

Answer 1

错误是自我解释的。您正在尝试加载太大的图片。

Canvas: trying to draw too large(111300000bytes) bitmap.

您在ImageButton或ImageView上设置的一个可绘制来源太大了。你可以：

手动缩放图像
在代码中执行缩放并在之后设置图像

Answer 2

java.lang.RuntimeException: Canvas: trying to draw too large(111300000bytes) bitmap.

如您所见，您正在尝试显示太大的图像。检查包含的位图资源的大小。

Answer 3

您正在显示大小 111.3 mb 的图片，该图片太大而无法处理您需要在显示之前压缩和缩放到某个较小的版本。在这里你可以扩展你的形象。

Bitmap scaled = Bitmap.createScaledBitmap(originalBitmap, 120, 120, false);

更多here 并使用

进行压缩

ByteArrayOutputStream out = new ByteArrayOutputStream();
scaledBitmap.compress(Bitmap.CompressFormat.JPEG, 85, out);
